View Full Version : A stretched video image needs to be recoded

Hello

I have an MP4 video which has a stretched image. I am familiar with Handbrake and recently saw a reference to a program called YodaResizeCalculator.

Some thread I found from years back plus the Handbrake manual page talk about anamorphic, anamorphic off, loose anamorphic and strict anamorphic.

If anything works so that I could even see some change, I'm ready to fiddle with it if I can't calculate it perfectly.



First I'll ask this: is the Command Line Interface within Handbrake on the Video tab where I have used threads=1?

If so, the Handbrake manual has some code to put in that to perhaps _unstretch_ the image on my video sample which is
verically distortorted. I didn't even know that was possible.

The source is unknown. It was in a pile of file shares so MediaInfo is all I have to analyze. The format is MP4.

I can supply more details.

If a sample is needed I can make a short clip in MKXToolnix.

A little more on this topic. I retraced my steps and found the
actual source which is Vimeo.

https://vimeo.com/401020599


That link shows a photo where everything looks ok: a still photo from the play or some such.

But on Vimeo play you see the distortion. So the distortion is at that source- very likely from a screen capture of the play when broadcast.

I didn't want to lose it so I let it play and the 3DYoutube capture tool was able to save it for me. It introduces more variables but that was the history.

It honestly looks like it came from a 720x480 anamorphic source which was probably flagged as 16:9 and was supposed to be resized to 848x480, but instead, whoever encoded it, assumed that it was 4:3 and added the pillarbox (the black you see on the left and on the right). My advice for your own personal usage / archival purpose would be:

- DO NOT capture it, it will mess up the framerate and other things, Download it with JDownloader instead (if you really have to as I assume the copyright expired; remember that we don't help with any illegal things here).
- Crop the black borders
- Resize to 16:9 like Spline64Resize(848, 480)

done.

(and... I'm done for 2020, Happy New Year everyone! :D)
